I have sth. to eat.这里不定式用的是主动.The building to be built will I have something to eat 这里的不定式为什么要用to eat而不是to be eaten 动词不定式I give the dog a bone to eat.为什么是to eat 不是to be eaten 这里不定式的时态问题have to be built 什么时态啊（这里应该也有被动语气吧）和have been buil The plans will have to be revised 改为主动语态 I have a bog house to live in.这里的不定式用to do 形式而不同to be done 形 主动表被动的句型有哪些?have sth to do 和have sth to be done有什么区别? 有关动词不定式的问题water will try to flow into the cell 这里的 to flow i 为什么这里要用不定式,这里的不定式做定语,I've got something to eat.（我有东西吃） it is going to be built. 这里的be是什么用法?谓语是哪个?
